In how many pairs the chromosomes in a karyotype match up?
23
Why is it important that new DNA be identical to the original?
The number of Chromosomes stay the same when the cell divides because before a cell divides it produces new copies of the Chromosomes in the nucleus so when division takes place two genetically identical 'daughter cells', containing the same genes, are formed. This is Mitosis, hope this helps =]
How many chromosomes do birds have?
Nearly each species of bird has its own unique number of chromosomes. It can be very difficult to determine the exact number because many of these chromosomes are highly fragmented into multiple 'microchromosomes.' In short, the answer is: "It depends..."
Chromosomes are made out of what molecule?
Chromosomes are DNA, which is made of sequences of nucleotides. Also there are some supporting factors such as proteint which help with it's structure and functioning. Nucleotides are molecules with a carbon-skeleton structure, about 3 small rings in size each. They bind in strings to other nucleotides quite strongly. One string binds less strongly to another string, but only if the nucleotides match (largely). In DNA there are four nucleotides, Adenine and Thymine which match, and Guanine and Cytosine which match.
Are chromosomes a part of every living cell?
No. Red Blood and some other cells do not have chromosomes.
What are chromosomes that match from the sperm and egg?
homologues
Do any chromosomes match another in a sex cell?
Yes infact ther are many chromosomes that match each oher ina sex cell.

Yes infact ther are many chromosomes that match each oher ina sex cell.
What are the only pair of human chromosomes that do not always match?
69

What makes mutations happen?
A mutation in humans is caused by a misconnection of DNA chromosomes and cells. Not all mutations are genetics some are just a fluke with the DNA match up.
Why must the quality and quantity of DNA in cells remain the same from generation to generation?
If it changed too fast then it would be difficult for the chromosomes to match up and offspring could not be produced. The quality must be maintained or proteins and other systems will not work correctly.

Why would it be much more difficult to construct a karyotype of unstained chromosomes?
it would be much more difficult to see the banding patterns
Can a man and a dog successfully conceive?
Human and Dog chromosomes do not match up. the egg would be fertilized but then DIE after the first couple of cell divisions. That's what makes it appealing to some.
